JIPMER Chemistry Mock Test - 1 - Question 1

The electrophile involved in the sulphonation of benzene is

Detailed Solution for JIPMER Chemistry Mock Test - 1 - Question 1
Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO2+) and sulfur trioxide (SO3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid 
Concentrated sulphuric acid contains traces of SO3 due to slight dissociation of the acid.
Dissociation:  This is a reversible splitting up of a compound. In this case, the sulphuric acid splits into water and SO3, and at the same time these combine back together again to make sulphuric acid. The overall effect is that concentrated sulphuric acid contains small amounts of SO3.
Fuming sulphuric acid, H2S2O7, can be thought of as a solution of SO3 in sulphuric acid - and so is a much richer source of the SO3.

JIPMER Chemistry Mock Test - 1 - Question 12

The heat of neutralisation, when 0.5 mole of HNO₃ solution is added to 0.2 moles of NaOH solution, is (Heat of neutralisation = 57 KJ-mol-1)

Detailed Solution for JIPMER Chemistry Mock Test - 1 - Question 12
HNO3=0.5 mol then ΔH =57KJ-mol-1we have already 0.2 mol of NaOHwhen 1 mol of NaoH are neutralized heat released =57 KJ-mol-10.2 mol of NaOH are neutralized heat released = 57 multiply 0.2=11.4 KJ-mol-1
